PATENT SlPHON-HEAD.

SPECIFICATION forming part of Letters Patent No. 618,616, dated January31, 1899.

Application tied Aprii 15, 189s.

To @ZZ whom, t may concern:

Beit known that I, CHARLES DE. QUILT.- FELDT, a citizen of the UnitedStates, residing at Amityville, in the county of Suffolk and State ofNew York, have invented certain new and useful Improvements inSiphon-Heads, ot' which the following is a specification.

This invention relates to improvements in Siphon-heads which are appliedto that class of siphons charged with mineral waters and in which thevalve is actuated in downward direction by a suitable spring against thevalve-seat at the upper end of the Siphon-tube with sufcient force toprevent the undue discharge of water or gas, but not so forcible as toprevent the water or gas escaping should the siphon be overcharged; andthe invention relates more specifically to certain improvements on theSiphon-head for which Letters Patent were granted on June 22, 1897, toEmil Stahl, No. 585,165, saidimprovement being designed with a view toso .constructing the Siphon-head that it can be taken apart at the topfor the purpose of repair and be put together again without removing thehead from the bottle, which operation often causes breakage of thebottle-neck, and that it produces the better and more reliable closingof the Siphon-head and prevents the escape of gas and water fromV thesame.

In the accompanying drawings, Figure l is a longitudinal verticalsection through my improved Siphon-head and the bottle to which it isapplied, the valve being shown in closed position; and Fig. 2 is asimilar section, the valve being shown in open position.

Similar letters of reference indicate corresponding parts. l

A indicates the bottle, B the tube extending down into the bottle, thesame being applied at its upper end into a socket C, that is providedwith an annular iange C and with a valve-seat C2 at its upper part, and,D indicates a rubber gasket, which is applied to the mouth of thebottle A and fits under the flange C.

E indicates the tubular casing of the siphon-head, which is providedwith a spout or nozzle E and is internally screw-threaded in itsenlarged base portion,into which is screwed a screw-nut F, whereby thesiphonhead is connected to the bottle A, so that the rubber Serial No.677,702. (No model.)

gasket D is compressed between the said casing E, the socket C and itsliange, and the mouth of the bottle, whereby a hermetic closure isprovided, which prevents the escape of gas or water, excepting throughthe proper channel-*that is to say, through the spout.

The construction so far as described is usual and well known and noclaim is made thereto.

The novel features of the invention lie in that portion of theSiphon-head which is arranged above the valve-seat C2.

G indicates the Valve,which is guided in the casing E and is of suitableconstruction, said valve being provided at its lower end with a headedneck G', upon which is applied a rubber or other elastic cup or thimbleH, which at its upper part is provided with an annular flange h. Thelower closed part of the elastic or yielding cup H is a packing to thevalve when it is closed against the valveseat C2, while the annularflange or lip h also acts as a packing or gas-check. The opening throughthe tubular casing E of the siphonhead is wider at the top and tapersdownwardly to an intermediate point ce, where the saidY casing iscontracted, as it were, while below the point ct and around thevalve-seat O2 the said casing flares or gradually enlarges. By reason ofthe gradual contraction down to the point ct the valve-head G can bereadily pushed down to the proper position, while the enlargement belowthe point a permits the operative portion of the valve-that is to say,that portion provided with the yielding cup-to have free play down tothe valve-seat. The cushioned or padded surface of the valve G, whichcan be of any desired shape, hermetically seals the Siphon-head againstinward or outward pressure until this pressure is released by theoperation of the lever 1,' which works through a side opening e in thecasing E and projects at its inner end into a transverse opening g inthe valve G. If the siphon is overcharged, however, the valve will beraised automatically. rlhe valve is pressed normally down against thevalve-seat by means of a helical spring J, which is coiled around theupwardly-projecting valve-spindle G', said spring being seated at itslower end upon the valve G and at its upper end against the top of thescrew-cap K, which is screwed onto the externally-screw-threadedupperend of the casing E. The cap K is provided with adownwardly-projecting guidesocket k, into which when the cap is screweddown tight the upper end g of the valvespindle is guided and whereby thevalve is centered within the siphon-head- When the siphon is to becharged with water and gas, the valve is raised from the valve-seat ofthe Siphon-tube by pressing upon the operating-lever I, whereupon theannular iiange or lip II of the yielding cup or thimble becomescompressed and is deflected by contact below the point a with the Haringwall of the casing, so that the said flange curls or curves to form aconcavity, which provides a gas-check and a perfect packing against theescape of gas or water, excepting through the discharge spout E'. Theaforesaid guidesocket on the under side of the cap K for the upper endof the valve-spindle performs two functions. First, it forms a bearingfor the upper end of the valve-spindle, which would otherwise be turnedout of the line of its proper axial movement and cause leakage, and,second, the valve can only be raised sufficiently high to allow the freepassage of water when the siphon is charged or discharged; but saidsocket does not allow the gas-check to be forced upward higher than tothe narrow or contracted part of the casing at a, thereby preventingleakage through the side openinge in the casing. In other words, by theabutment of the valve-spindle against the cap K or a portion thereof theupward movement of the valve is limited.

The operating-lever I of the valve mechanism is fulcrumed on the casingE at e at the lower portion of the opening e, said opening being largeenough to admit the lever through the same and into the opening g in thevalve a pin, while the lever is correspondingly reof the handle of thevalve, will engage at the side of and above the side opening e in thecasing, so that the said lever is, as it were, locked between the threepoints ef, and i', thereby preventing the lever from moving loosely upor down, as in other Siphon-h eads of this class. The lever cannot beremoved without rst unscrewing the cap on the Siphonhead, so as torelease the spring-pressure.

Having thus described my invention, what I claim is- 1. In a siphonhead,the combination of a casin g, a detachable screw-cap for said easinghaving an interior guide-socket, a spring-controlled valve guided in thecasing, a spindle on said valve, said socket when the cap is screweddown tight serving as a guide for the upper end of said spindle, andmeans for aetuating the valve, substantially as set forth.

2. In the Siphon-head, the combination of the casing contracted at anintermediate point and Haring below said point,and a valve in saidcasing having a packing with a circumferential lip or iange thereon,located within said flaring part of the casing and adapted to bedeiiected or bent by contact with the wall of said iiaring part when thevalve is raised, so as to form a gas and water check7 substantially asset forth.

In testimony that I claim the foregoing as myinvention I have signed myname in presence of two subscribing witnesses.
